The Aberdeen business has paid more than s3 million to Alberta based IROC Energy Services Partnership.

Canada Tech specialises in tools and systems which measure pressure and temperature in oil and gas wells.

Pascal Bartette, Reservoir Group chief executive officer, said: "We welcome Canada Tech and its employees to the Reservoir Group club.

"Canada Tech has developed leading technical solutions for well monitoring which complement the first class solutions already available from our existing group company, Omega Data Services.

"With increasingly complex well completions, understanding downhole conditions is critical to maximising value from the reservoir.

"The combination of Reservoir Group's international network and advanced monitoring solutions offers tremendous opportunities to our well monitoring business line."

Tom Alford, president and chief executive officer of IROC, said: "We believe that this is the best outcome for Canada Tech's employees, customers and the IROC stakeholders.

"The sale of Canada Tech completes the divestiture of the last business in IROC's technology services business segment and will allow our management team to focus IROC's strategy on continuing to grow our various drilling and production services businesses."
